certain new and useful Improvements in Apparatus for Charging Liquor with The objects of our invention are to introduce the liquid under pressure into a tank, imparta swirling whirling motion to said liquid as it enters the tank and simultaneously therewith inject a jet of highly compressed gas throughthe swirling stream of liquid so as tovthoroughly and intimately mix and mingle the liquid and gas together as they'enter the tank and thereby produce high and uniform carbonation of the liquid. at an extremely rapid speed. To accomplish these and other objects we have devised a simple and exceedingly eflicient apparatus nected thereto. Fig. 3 is including a pump for the liquid, a mixing tank suitably connected to 'said pump, by piping, a device within the tank having oblique defiecting'or mixing blades or vanes against which the liquid impinges as it flows from the pump piping and an injecting nozzle suitably connected to a source of gas under high compression which'directs a jet of gas upon the liquid as it flows from the pump piping and is converted into a swirl-- ing whirling stream by the oblique blades or vanes.

The manner in which we carry. out our im- Drovement'Will be fully and clearly set forth and described in the following specification and particularly pointed out in the appended claims, reference being had to the accompanying drawings in which apreferred embodiment or adaptation of our imgas is shown.

In referring to the preferred embodiment or adaptation of our improved apparatus for charging liquid with gas shown. in the h accompanying drawings in detail like Enumerals indicatecorresponding parts.-

Our improvement in .the art of'charging liquid with gas briefly stated consists in introducing a stream of liquid under pressure into a suitable tank or container and against oblique deflecting surfaces which impart: a swirling motion 'to the said streamand simultaneously directing a;jet of highly com} pressed gasagainst the swirling stream so that uniform, even and thorough carbonation of the liquid is effected.

. Qur improvementv as shown in the accom-- panying drawings and described in-the fol-. lowing specification is'chiefly used in car.- bonating beer and similar liquids. v

As shown the preferred embodiment of our improved apparatus comprises a mix- 7 '95 ing tank or container, a pump for the liquid suitably connected by piping to the mixing gas under high pressure.

V tank or container and piping for supplying proved apparatus for charging liquid with The mixing tank or container consists of J a cylindrical body 1, mounted in vertical position' on a stand or support 2, a closure. plate 3, for the lower end of said body n'd a head of closure plate 4' for the upper end of said .body. The heador upper closure plate 4, is constructed substantially as shown in Figs. 1, 2, 3, 4 and 8, principally 8, and is provided'with an annular flange '5,

through which bolts 6 are fitted .to detach-f ably securethe head to the'bod y 1, acenter vertically projecting valve casing v7 having a taperingvalve seat 8, at its lower end which opens into the interior of'the tank,- a

3-3 .in number and in order to securely fasten horizontal holldwportion 9 having an opened pipe socket 11, into which a. ,pipe 12 screwswhich extends from a suitable source ofgas under pressure.

An annular collar 13,,is fittedwithin' the valve casing through the reduced openingof which the upper portion of a valve stem 14 projects. is mounted upon anintermediate portion of the valve stem and is operatively arranged relatively to the valve seat 8. The valve is preferably flattened or cut away on one side,

I so that the gas passage is never entirely'close'd position on one side of the tank or conas shown at 16 in Fig. 7. The valve 15,"is normally maintained in closed position relatively to the valve seat 8, both by gravity and by the tension of a spiral spring 17,. ar-

ranged in the valve casing and adapted to press down upon a collar 18 on the upper end of the valve stem. The tension of the spring 17 is regulated by a flanged nut 19,. fitted in the. upper end of the spring and mounted on the lower extremity of a screw bar' 20, which is fitted through a screw threaded central opening-in a screw cap 21, closing the upper end of the valve casing. A manually operated turning wheel 22, is attached to the upperprojecting end of the bar 20, and a stuffing-box 23, is arranged on the screw cap to prevent the escape of gas through .the upper end of the valve casing.

- The lower portion of the valve stem depends vertically down within the tank body and v carries a float 24 at-its lower extremity. The

object of the float is to raise the valve 15. as the liquid. accumulates'in the tank 1, so as to supply a su'fficient amount of gas to establish a pressure to flow of liquid. I

hung pendant from the upper head and depends centrally within the body'ofthe tank.

, or container. The preferable form of mijxing device or shell is shown in Figs. 3 and 5 and consists of an upper circular band or ring 25, a lower band or ring 26, and an intermediate taperingwide band 27, which extends, between and merges at'i'ts respective top. and. bottom with the'bands 25 and 26., Deflecting blades or vanes 28 are arranged within the upper-band which extend ob- ..liqueIy, and similar oblique bladesor vanes =29 are also arranged inthetapering whom shaped band 27, as shown in Fig. 9. For some purposes one of these sets of deflecting blades or vanes may be dispensed with, the remaining set being suflicient. The purpose of these blades will be'fullyset forth farther on. The blades or. vanes 29 located in the tapering conical band 27 are preferably four or rivets 32, or A truncated conical valve 15- prevent the further infrom a common center-sleeve 31 to the annular tapering wall of the band. The blades 29 are preferably. formed in the peculiar curved shape shown in Fig. 9 and are rigidly fastened to the partitions30 by bolts other suitable fastening means.

The valve stem 14 has the lower portion thereof below the cone valve 15, slidably fittedthrough the sleeve 31,- as shown in Fig. 3, whichthus supports and centers the same.

An indicating gage is arranged in vertical tainer for indicating the liquid level Within the tank which comprises a glass tube 33, a pipe 34 leading from the upper endthereof I and connected to: the head through which it its outer end-to apipe 41, which extends from a pressure pump 42, tothe tank or container. The pipe 40-is provided with a shut off valve 43, and the pipe 41,". extends horizontally to one side of the tank or container, then bends vertically up extending along the side of the tank to a point slightly above the'head where it bends horizontally in;and-c,o1:ir 1ectsv to a hollow horizontal coupl1ng'44, formedfin the head. The inner portion of the coupling extends to and com municates with the interior-of the mixing shell at the upper-end thereof. If desired portions of the pipe 41 may be constructed of suitable flexible hose. A short horizontal pipe 45 extends inwardly from the pipe 41 and connects to the tank or container near the'lower end thereof and a three way valve 46 is located at'the juncture of said pipes 41 and 45,- A. shut ofl valve- 47 is also located n the lower horizontal portion of the pipe.41. I

I An-outlet pipe 48 is connected to the tank ;or container preferably-through the lower closureplate 3, as shown in Fig. *3, and extends to any desired receptacle or receiving tank.-

shut ofl' valve 49 is placed in this pipe 48. F I

I We prefer to use the gas known as carbonic acid gas and undeif' high pressure and conduct it from a suitable? supply receptacle (not shown) through the pipe 12 and socket 11 to a point within the valve casing above the cone valve as shown in Fig. 8. A suitable shut off and regulating valve 50 is placed in the pipe 12 and a'gas pressure indicating gage 51 is also connected to said pipe 12. A pipe 52 is connected to the head and is provided with a shut ofl' valve 53, which when open permits the air within the tank or container to be forced out as the liquid enters.

We preferably operate our improved apparatus as follows: The valve 53 being opened and the three way valve 46 being turned to permitthe liquid to How into the tank through the lower horizontal pipe 45, the pump 4:2 is started and the tank gradually filled with liquid. When the tank is filled to the desired point as indicated in the glass 33 the valve 53 of the air outlet pipe is closed and the three Way valve 46 is turned to shut off the pipe 45, and-open the passage for the flow of liquid-through the upper position of the pipe 41 to and through the coupling 44, and the mixing shell from where it flows downwardly into the tank. At the same time the shut off valve .49 of the outlet pipe is opened permitting the liquid to flow out from the tank and the gas supply valve is opened to allow the gas to pass into the valve casing and thence downward past the cone valve and into the mixing shell. As the liquid enters the mixing chamber it impinges upon the oblique blades or vanes 28 and 29 and is deflected by the same being given a swirling motion, and at the same time the gas issues forth from the lower end of the valve. casing under high pressure 'and contacts, mixes and commingles with the liquid forming an even and uniform mixture and 'produc ing perfect and efficient carbonation. The breaking of the stream of liquid by the vanes as described releases and separates some of the gases contained in and forming the liquid and also separates and divides the liquid into a multiplicity of minute particles which readily and easily mix and combine with the carbonic acid gas.

While our improvement in the art of charging liquids with gas is designed chiefly for carbonating beer and similar witnesses. I

struction herein shown and described but desire to avail ourselves of all such variat1ons, alterations, modifications and changes as fairlyfall within the scope of the appended claims or may be constructed to be within the scope thereof by invoking the doctrine of equivalents.
